War Galleys are larger than normal galleys. Equipped with ballista or catapults.
Used throughout the Mediterranean since the 11th century. War Galleys are larger than normal galleys, and carry more tonnage as a result of being equipped with siege weapons like ballista or catapults, and having a larger compliment of oarsmen and soldiers onboard. The standard tactic for engaging is to disable the opposing ships' sails then ram and board it.
